My invention relates to an air moistener with water absorbent channeled material dipping with its sides into a liquid container with a central flue. According to my invention the sheets of the absorbent material are arranged one over the other with spaces between them and with openings in the water absorbent materials. With such devices a very good result is attained because the air is forced through a great number of channels and openings formed on both sides by moistened surfaces and therefore the air is saturated in a high degree with water and in meantime dust and soot particles are delivered to the water absorbent materials. By these means a pure and wholly moistened air is obtained in a very short time.

By such devices the movement of the airis produced by a heating body or by a ventilator and two such forms of construction are illustrated in the accompanying drawing.

Fig. l is an air moistener with siX sheets of water absorbent material arranged one over the other and with openings lying in a shifted manner and the whole over a heating body especially of the radiator type.

Fig. 2 is a longitudinal section according to line A-B of the Fig. 1 the supporting means on the sections of the absorbent materials not being shown.

Fig. 3 is a fro-nt View of the air moistener with only three sheets of the water absorbent material and with a perforated covering.

Fig. 4 is a section through an air moistener with crossed sheets of the water absorbent material and brought in working by a ventilator.

Fig. 5 is a top view of the Fig. 4 with the covering removed and only some openings shown in the water absorbent material.

Fig. 6 is a sectional view illustrating the opening in the absorbent sheets.

Fig. 7 is a perspective View of the water container with a central flue.

The water container l is attached according to Figs. 1-3 to a heating body of the radiator type 2 from which the warm air is ascending and iiows through the opening 3 into the air moistener. This air moistener is composed of a plurality of sheets of the water absorbent materials ll, 5, 6, 1, 8, and 9 lying one over the other. According to the constructional example of Figs. 1 and 4 the apparatus consists of six sheets of water absorbent material but generally the air moistener will be constructed according to Fig. 3 where only three sheets of Water absorbent materials lie one (Ci. 261-l04) over the other. The number of such sheets however may be increased or reduced.

These sheets of water absorbent materials are dipped With both ends into the water container l (Fig. 3) and are supported by a trellis-work or by little iron bars which are indicated in Figures l, 2, and 3 by the numeral i8, so that channels are formed between the sheets of the water absorbent material. If these sheets consist of clay no supporting means are necessary.

According to Fig. 1 the openings iil, l l, l2, i3, ill, and l5 are shifted in such a manner that the air is forced toascend in zigzag through the nozzles la as shown by the different arrows and nally the air will escape outwards saturated in a high degree with moisture. A part of the air can also flow outwards along the channel as shown by the arrows. The whole apparatus can be closed by a perforated covering i6 illustrated in Figs. 3 and 4. v

According to Figs. 4 and 5 the sheets a and Z7` of water absorbent material are lying one over the other in a crossed manner and are dipping with both ends into the water container l placed upon a stand c in turn adapted to rest upon a radiator. The supporting bars i3 are not shown in that figure. A ventilator f which will be driven by an electromotor d is placed on the hollow space 3 and which ventilator presses the air through the openings e provided in the different sheets of Water absorbent material. A perforated covering i6 closes the apparatus.

According to Figs. 4 and 5 the openings e are distributed over the whole surface of the water absorbent materials and these openings can be formed in a tubular manner preferably of absorbent material and integral with the sheets separately affixed thereto, as shown in Fig. 6 so that the air touches a greater surface of the moistened matter in iiowing through these openings. These tubes under and over the openings of the sheets can be formed as nozzles.

Apparatus according to Figs. 4 and 5 can also be placed over heating bodies of the radiator type or the like and such apparatus according to Figs. 1 3 can be used in connection with ventilators.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:

l. An air moistener for heating appliances of the radiator type comprising a casing of substantially rectangular form having a central air ue open at top and bottom and a water reser- Voir located outside of said flue, a plurality of superimposed U-shaped sheets of absorbent material arranged above and over said flue and having their ends depending into said reservoir, said sheets being spaced whereby a plurality of air channels open at their ends are formed, and a ventilator in said flue for substantially vertically forcing the air to be moistened through the apparatus, said casing being adapted to rest on the heating appliances.

2. An air moistener for heating appliances of the radiator type comprising a casing of substantially rectangular form having a central air iiue open at top and bottom and a Water reservoir located outside of said flue, a plurality of superimposed U-shaped sheets of absorbent material arranged above and over said flue and having their ends depending into said reservoir, said sheets being spaced whereby a plurality of air channels open at their ends are formed, and means in said sheets forming openings for penetration by the air to be moistened, said means being thicker than the thickness of said sheets whereby a tubular canal is formed so that the penetrating air comes in Contact with the greater mass of the absorbent material, said casing being adapted to rest on the heating appliances.

3. An air moistener for heating appliances of the radiator type comprising a casing of substantially rectangular form having a central air flue open at top and bottom and a water reservoir located outside of said flue, a plurality of superimposed U-shaped sheets of absorbent material arranged above and over said flue and having their ends depending into said reservoir, said Y sheets being spaced whereby a plurality of air channels open at their ends are formed, and means in said sheets forming openings for penetration by the air to be moistened, said means being'thicker than the thickness of said sheets whereby a tubular canal is formed so that the penetrating air comes in Contact with the greater mass of the absorbent material, said openings being arranged in staggered relation relative to each sheet, said casing being adapted to rest on the heating appliances.
